Abstract: A color image sensor including an array of pixels is formed in a semiconductor layer having a back side that receives an illumination. Insulated conductive walls penetrate into the semiconductor layer from the back side and separate the pixels from one another. For each pixel, a color pixel penetrates into from 5 to 30% of a thickness of the semiconductor layer from the back side and occupies at least 90% of the surface area delimited by the walls. An electrically-conductive layer extends from the lateral wall of the filter all the way to the walls.
